Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a safety device for a meat chopper in which a meat chunk pumping device section and a meat chunk charging section can be separately attached and detached.

[Conventional technology]

Conventionally, the meat chunk feeding device and the meat chunk feeding unit (hopper) can be separately attached and detached from the main body, and when the meat chunk is manually pushed into the meat chunk feeding unit, the There is a safety guard on the top to prevent your hands from reaching easily.

[Problems to be solved by the device]

However, if the hopper part is removed for cleaning or inspection, the safety guard is also removed together, so that the rotating part of the meat chunk pumping device can easily be reached. Here, if the motor is suddenly turned on and the motor is driven, there is a risk that the hand is caught in the rotating portion of the meat chunk feeding device and an accident such as finger cutting occurs.

The object of the present invention is to eliminate the above-mentioned drawbacks of the prior art,
The point is to increase the safety of this type of meat chopper.

[Means for solving the problem]

According to the present invention, a hopper that has a safety guard is provided on an upper part of a housing that houses a motor and a power transmission device that transmits the power of the motor, and the hopper is provided to be detachable so as to engage with the power transmission device. In a meat chopper in which the meat pumping device is provided so as to project in the horizontal direction of the housing and is detachably mounted, a pin having a notch is fixed to the hopper in parallel with the attachment / detachment direction, and the position where the pin engages with the housing A lock pin and a spring are loosely fitted to, a hole parallel to the attachment / detachment direction of the meat lump pumping device is provided at a position that engages with the lock pin, and the meat lump pumping device is provided with a guide pin that is loosely fitted in the hole. This is achieved by removing the hopper from the housing only when the meat pumping device is disengaged from the power transmission device.

[Action]

When the meat chunk pumping device is moved, the detent guide pin is disengaged from the notch of the pin, and the engagement between the guide pin and the pin is released. By releasing the engagement between the guide pin and the pin,
The pin or hopper can be removed from the housing. At this time, the lock pin is pushed by the spring,
Since the lock pin closes the hole of the rotation stop guide pin, the meat chunk pumping device cannot be installed alone.

When the rotation stop guide pin of the meat chunk pumping device is engaged with the notch of the pin, the pin catches on the rotation stop guide pin and the hopper cannot be removed from the housing.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a side view showing an embodiment of a safety device for a meat chopper of the present invention.

In the figure, a motor 2 is provided inside the housing 1,
A power transmission device 3 that transmits the power is provided.
A hopper 4 is detachably attached to the upper surface of the housing 1. The hopper 4 is provided with a safety guard 5 and a meat dish 6 on which the unprocessed meat mass is placed. On the outer surface of the upper part of the housing 1, a meat pumping device 7 is mounted so as to project in the horizontal direction, and is connected to the power transmission device 3.

A rotation stop guide pin 8 is fixed to the upper portion of the meat mass pumping device 7, and the guide pin 8 is inserted into a hole 9 formed in the left and right direction of the housing 1. A pin 11 having a notch 10 is fixed to the hopper 4, and the pin 11 is inserted into a hole 12 formed in the housing 1 in the vertical direction. A lock pin 13 is loosely fitted in the hole 12 via a spring 14, and a set screw 15 provided in the housing 1 is engaged with a long groove 16 formed in the lock pin 13 to prevent the lock pin 13 from coming off. There is.
The holes 9 and 12 are formed so as to be orthogonal to each other.

2 and 3 are views showing a fitting state of the rotation stop guide pin 8 and the pin 11 when the hopper 4 and the meat chunk pumping device 7 are properly mounted on the housing 1, and FIG. FIG. 3 is an enlarged view of part A in the figure, and FIG. 3 is a sectional view taken along line BB in FIG.

In the above structure, the lock pin 13 is pushed by the pin 11 provided on the hopper 4, and the lock pin 13 is pushed by the spring 14.
13 The tip portion is always in contact with the tip of the pin 11. In the notch 10 of the pin 11, a rotation stop guide pin 8 of the meat chunk pumping device 7 is provided.
Are engaged. At this time, the hopper 4 cannot be removed from the housing 1 by the rotation stop guide pin 8.

FIG. 4 and FIG. 5 show a state in which the hopper 4 and the meat chunk pumping device 7 are removed from the housing 1.
The drawing is an enlarged view of a portion A of FIG. 1 showing a state of being removed, and FIG.

When the meat chunk pumping device 7 is moved in the direction of the arrow in FIG. 4 and the detent guide pin 8 is disengaged from the notch 10 in the pin 11,
The hopper 4 can be removed from the housing 1.

At this time, the lock pin 13 is pushed by the spring 14 and moves in the direction of the arrow in FIG. Since the lock pin 13 closes the hole 9 of the rotation stop guide pin 8, the meat mass pumping device 7 cannot be attached alone.

[Effect of device]

According to the present invention, the detent guide pin of the meat chunk pumping device is engaged with the pin of the hopper to limit the order of attachment / detachment, and the meat chunk pumping device must be removed before removing the hopper. In addition, in order to install the meat chunk feeding device, it cannot be installed unless the hopper is installed first.

Therefore, with the hopper removed, always
Since the meat pumping device is also removed, it is impossible to drive the meat pumping device with the hopper removed.
In addition, since the hopper to which the safety guard is fixed is always attached when the meat chunk pumping device is mounted, the rotating portion of the meat chunk pumping device cannot be easily reached.

By adopting the structure as described above, it is possible to provide a meat chopper with high safety that prevents an accident such as a hand getting caught in the meat chunk pumping device.
